Application filed December 2, 1913. Serial No. 804.188.

To all NJ/10m it may concern:

Be it known that I, J our: ALBERT Os'rnN- mane, a citizen of the United States, residin at R. R. No. 9, Campbell. in the county Santa Clara and State of California, have invented certain new and useful Improvements in Motor-Flows, of which the following is a specification.

My invention relates to new and useful improvements in motor plows and more particularly to a combined motor and plow having a long wheel base for working, and a short wheel base for turning and maneuvering" the machine into position for starting, a new furrow, which is very necessary in orchard plowing.

An object of my invention is to provide a motor plow for the above purpose, and one in which the entire motor and plows will be under the control of one operator seated on said machine, and one in which the plows may be adjusted by the operator to such'an angle that they will take a desiredposition in line with either traction wheel, thus permitting furrows to be cut close to the trees in an orchard in either direaction, at the same time cutting straight furrows and pulling from the center of thc plow frame. this center pull giving an even draft to both traction wheels.

A further object is to provide means whereby motor plows may be of as light weight as possible, to avoid packing the soil.

A further object is to provide. means by which the motor power may be transmitted to the wheels that carry the plows.

A further object is to provide means by which the plows may be worked on either side of a central power transmission.

A further object is to provide means by which the furrow wheel may be driven by said transmitted power.

A further object is to provide means by which the plows may he raised up clear from the ground when found necessary.

Finally, an important object of my invention is to provide a motor plowof the character described which will be strong, durable, simple and efficient, and comparatively inexpensive to construct, and also one which will not be likely to get out of working order.

With these and various other objects in view, my invention has relation to certain novel features of construction and operation, an example of which is described in the following s n".-ification, and illustrated in the accom ninving drawings; wherein:

Figure 1 is a side elevation of my motor plow complete. Fig. 2 is a plan view of my motor plow. parts being broken away. Fig. is a sectional view on line A-A of Fig. 2. Fig. l is a plan view of the plow beam and the connections thereto. Fig. 5 is a detail view of a portion of the steering, mechanism. Fig. U is a detail view of a portion of the stccring mechanism showing its rciation to the friction drum.

Referring now more particularly to the drawings, wherein like reference numerals designate, similar parts throughout the several vie\vs,--,t designates the main frame constructed of suitable material, prefcrably of steel of the proper width and thickness, bent and formed in shape as shown in the drawings, the same being bolted together in a strong manner. Auxiliary frame 2 is conncctcd to frame 1 by pivot pin 8 at the top thereof, and by pivot pin #1 at the bottom thereof. and is turnable on said pins. Plow bcam 5 is conncctial to said frame 2 by pivot pin .3 and is turnable thereon. Fastencd to plow beam 5 are arms 7, the same being adjustable on plow beam 5, for the purpose of carrying one or more disk plows as shown at 8. Connected to plow beam 5 is arm 9. At the outer end of said arm 9 is connected furrow wheel 10 by stud 11, said furrow wheel. may be made of cast iron or any other suitable material, having a gear 12 attached thereto, the same being driven by pinion gear 13 attached to shaft 14:, near the end thereof, said shaft being supported at the outer end thereof by arm 15 carrying shaft bearing" 17. said arm being fastened to arm 9 as shown at 16, said shaft 14: extending for *ard to frame 2 where the same is'connected to furrow wheel driving shaft 18 by universal joint 19. Said shaft 18 is supported by bearings 20 and 21 on auxiliary frame 2. On the forward end of shaft 18 is fastened beveled gear 22 connecting with beveled gear 23, which is keyed to sleeve 24. On the lower end of said sleeve 24 is keyed bevel gear 25. Sleeve 2& is turnable on pivot pin 3. Beveled gear 25 connects to beveled gear 26 which is keyed to main driving shaft 27. By these means the power is transmitted to shaft 18 and shaft 14, and thus to furrow wheel 10. Main driving shaft 27 is connected to motor 28 by disk clutch 29 and fly wheel 28. Said shaft 27 extends back a distance and is held in place on frame 1 by bearing 30. Keyed to the end of shaft 27 is beveled inion gear 31, which connects to differentia gear 32, said differential gear being connected to shaft 33, said shaft being held in place on frame 1 by bearings 34. On both ends of shaft 33 are keyed pinion gears 35; these gears come in contact with internal gear 36, on the inside and inner edge of traction wheels 37, said traction wheels being turnable on shaft 38, the same being held in place on frame 1 by clamps 39. The rear end of frame 1 is made arcuate in shape. In the center thereof is attached shaft by bearing 41. On the end of said shaft is pinion gear 42 adapted to engage gear rack 43, said gear rack being arcuate in shape. Said gear rack may be fastened to frame 2 in any secure manner. Shaft 40 extends forward and is held in place by hearing 44. On the end of said shaft 40 is spur gear 45, which comes in contact with spur gear 46, said gear being keyed to shaft 47, said shaft being kept in lace on frame 1 by bearings 48 and 49.

n the forward end of shaft 47 is keyed an internal and external gear 50; the internal portion thereof comes in contact with pinion gear 51 keyed to shaft 52, said shaft being held in place on rocker frame 55 by hearing 53 and bearing 54 on rocker frame 55, which is held in place and operates on pivot 56 supported b frame 1. Keyed to the forward end of shaft'52 is friction wheel 57,

. which when required comes in contact with the outside of friction drum 29 On the other end of rocker arm is friction wheel 58 keyed to shaft 59. On the inner end of said shaft 59 is keyed pinion gear 60, which comes in contact with the external part of gear 50, said shaft 59 being held in place on rocker frame 55 by bearing 61 and hearing 62. These gears and friction Wheels 57 and 58, are for the purpose of steering the motor plow by power from the motor 28, and the same is operated by steering arm 63, to which is connected steering rod 64, having a swivel joint at 64*, and connecting to one end ofbell crank 65 by pivot joint 64". Bell crank 65 is pivoted at 65". To the other end of hell crank 65 is connected a link by means of pivot joint 65, said link 65 being pivotally connected to rocker frame 55 at 651, and thus by turning steering arm 63 tothe right connects friction wheel 57 to the outside of friction drum 29 causing shaft 40 to revolve to the left with pinion gear 42 engaging gear rack 43 causes frame 1' to swing around to the right on traction wheels 37 and vice versa when steering arm 63 is turned to the left and friction wheel 58 is brought in contact with the outside of drum 29 Said clutch 29 is operated by spiral spring 29 and releasing 1,1 raeea lever 66to which is attached wire .cord 67 leading to bell crank foot lever treadle 68.

Spiral spring 29 engages clutch 29 and by pressing lever 68 gart way down said clutch 29 is released. y pressing said lever 68 clear down the wire cord 68 operates the a forward end of said shaft7 6 is keyed friction wheel 7 7 said friction wheel being held in place by bearing 78 on rocker arm 79, and operates when in connection with the outside of friction drum 29*. Connecting with rocker arm 79 is wire rope 80, extending back and connecting with bell crank foot lever 81.

When it becomes necessary to lift the plows 8 out of the ground, the operator presses down on the foot lever 81, which connects friction wheel 77 to the outside of friction drum 29 thereby revolving shaft 76 and worm gear 75, which inturn works chain drum 74, winding up chain 73. This draws up the forward ends of lever arms 7 O and forces down wheel 69, thereby' raising plows 8 out of the ground. On the end of lever 70 is fastened a short stud 82 which engages book 83 and holds lever arms 70 in.

place when plows 8 are raised out of'the ground, this allows the operator to take his foot ofi of the foot lever 81 which releases friction wheel 77, and the plows 8 are then held up clear of the ground by hook 83 engaging stud 82. Hook 83 is held in place by bracket 84 fastened to frame 2, and is operated by lever 85. Operators seat is shown at 86, which may be made of cast iron or any other suitable material. and of any shape desired. At the left of seat 86 is hell crank lever 87 connected to frame 2 by fulcrum pin 88. To bell crank lever 87 is connected iron rod 89 by bolt 90. The other end of said iron rod 89 is connected to plow beam 5 by bolt 91. This lever 87 is for the purpose of adjusting plows 8 in any required position, said lever 87 being held in place by notched bar 92, fastened to frame 2 by bolts 93. "While disk plows are shown and described, I do not wish to confine myself to them alone as any other form of plow or cultivator may be attached in the same or a similar way.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. The combination with a traction eng'ine of a plow frame and means for pivotally connecting the same to said traction engine, said plow frame havin a plurality of plows adjustably mounted t ereon and a posteriorly rojectin arm rigidly attached thereto, a rrow w eel mounted on said posteriorlyprojectin arm, and mechanism operativel connecte thereto by which said furrow wheel is driven cooperatively with said traction engine as shown and described.
